Functions

LLVM.Function — Method
LLVM.Function(mod::Module, name::String, ft::FunctionType)

Create a new function in the given module with the given name and function type.

source

Properties and operations

LLVM.function_type — Function
function_type(f::Function) -> LLVM.FunctionType

Get the function type of the given function. This returns a function type, as opposed to value_type which returns the pointer type of the function constant.

source
Base.empty! — Function
empty!(f::Function)

Delete the body of the given function, and convert the linkage to external.

source
LLVM.erase! — Method
erase!(f::Function)

Remove the given function from its parent module and free the object.

Warning

This function is unsafe because it does not check if the function is used elsewhere.

source
LLVM.personality — Function
personality(f::Function)

Get the personality function of the given function, or nothing if it has none.

source
LLVM.personality! — Function
personality!(f::Function, persfn::Function)

Set the personality function of the given function. Pass nothing to remove the personality function.

source
LLVM.callconv — Function
callconv(f::Function)

Get the calling convention of the given function.

source
callconv(call_inst::Instruction)

Get the calling convention of the given callable instruction.

source
LLVM.callconv! — Function
callconv!(f::Function, cc)

Set the calling convention of the given function.

source
callconv!(call_inst::Instruction, cc)

Set the calling convention of the given callable instruction.

source
LLVM.gc — Function
gc(f::Function)

Get the garbage collector name of the given function, or an empty string if it has none.

source
LLVM.gc! — Function
gc!(f::Function, name::String)

Set the garbage collector name of the given function.

source
LLVM.entry — Function
entry(f::Function) -> BasicBlock

Get the entry basic block of the given function.

source

Attributes

LLVM.function_attributes — Function
function_attributes(f::Function)

Get the attributes of the given function.

This is a mutable iterator, supporting push!, append! and delete!.

source
LLVM.parameter_attributes — Function
parameter_attributes(f::Function, idx::Integer)

Get the attributes of the given parameter of the given function.

This is a mutable iterator, supporting push!, append! and delete!.

source
LLVM.return_attributes — Function
return_attributes(f::Function)

Get the attributes of the return value of the given function.

This is a mutable iterator, supporting push!, append! and delete!.

source

Parameters

LLVM.parameters — Function
parameters(ft::LLVM.FunctionType)

Get the parameter types of the given function type.

source
parameters(f::Function)

Get an iterator over the parameters of the given function. These are values that can be used as inputs to other instructions.

source

Basic Blocks

LLVM.blocks — Function
blocks(f::Function)

Get an iterator over the basic blocks of the given function.

source
LLVM.prevblock — Function
prevblock(bb::BasicBlock)

Get the previous basic block of the given basic block, or nothing if there is none.

source
LLVM.nextblock — Function
nextblock(bb::BasicBlock)

Get the next basic block of the given basic block, or nothing if there is none.

source

Intrinsics

LLVM.name — Method
name(intr::LLVM.Intrinsic)

Get the name of the given intrinsic.

source
LLVM.name — Method
name(intr::LLVM.Intrinsic, params::Vector{<:LLVMType})

Get the name of the given overloaded intrinsic with the given parameter types.

source
LLVM.Function — Method
Function(mod::Module, intr::Intrinsic, params::Vector{<:LLVMType}=LLVMType[])

Get the declaration of the given intrinsic in the given module.

source
LLVM.FunctionType — Method
FunctionType(intr::Intrinsic, params::Vector{<:LLVMType}=LLVMType[])

Get the function type of the given intrinsic with the given parameter types.
